The soft start and braking device of the VersiComb series from PETER electronic, for motor ratings up to 11KW, represents an alternative with a good cost-performance ratio in order to replace star-delta starting in combination with a d.c. braking device.
The devices of the VersiComb II type enable soft start and wear-free braking of three-phase asynchronous motors. Their advantages in comparison with direct-on-line starting or star-delta starting are a torque increase without jerk and current reduction during the starting phase.
This gives the mechanical system and the drive components a longer life.
|
|
With the soft start device SAE 3 a bi-directional power semi-conductor is integrated into one of the phases.
By contolling its firing angle in a time-dependant manner only a small current flows into one of the phases.
The current is steadily increased until the max. current flow angle is reached.
In this way the max. torque is present which is sufficient enough to enable a save start even with drives having a large friction torque at standstill.
The current rise time (running-up time) and the initial torque of the motor can be seperately set.
The settingpotentiometers are accessible by removing the front cover.
When the max. current flow angle is present after the settable starting time has elapsed a relay contact shortens the power semi-conductor, thus removing the starting electronics from the circuitry.
Since only 1 phase is influenced, an asymmetric rotating field is generated which causes a higher thermal loss of the motor. |

Digistart is a multifunctional electronic starter with microcontroller. It is suitable for use on all the three-phase asynchronous induction motors, and assures :
- Starting management: All the traditional systems concerning motor starting (direct, star-delta, etc.) can draw a starting current that can vary between 7 and 9 times the motor rated current.
Digistart, can limit by simple adjustment, ina precise way, the current during the entire starting up phase.
- Protection of motor and driven machine: The starting up, the protection and the system automation imply the numerous elements installation making the electronic chassis complex and costly. Digistart provides supplementary functions that limits the need for additional equipment with a consequent reduction in cost of material, manpower and running costs.
- Progressive stop control: The impact of harsh stops on certain low inertia applications, especially pumps, induces mechanical shocks, hydraulic disturbance or noise pollution.
Digistart, by generating a voltage at the motor terminals during the deceleration phase, extends the time taken for the motor to come to rest. |

These soft starters are microprocessor controlled and are designed to work with asynchronous motors connected in open delta configuration. By using this technique the soft starter can handle more power than when connected in a conventional star circuit. Motors of up to 55kW open delta (37kW star)can be controlled with this range of units.
The M300 range limits the current during start-up and so it is more efficient. All settings are made through a touch panel which incorporates an Light emitting diode display.
They protect the mains supply from sags and damaging surges (transients), whilst reducing the current demand during start-up. |
